Simply being nerdy just isn’t going to cut it. If you wore your “nerd glasses because you thought you were so hipster,” that’s not enough of a blunder.

Halloween costumes do not count!

2 - You must have a creative title.

No "Puberty has been good to me." or "LOL I was random!" type titles. This is rule is entirely decided by the mods' discretion.

3 - Your blunder must have been at least 3 years ago

No "still blundering"

4 - Childhood photos are great, as long as they actually depict a blunder, and AS LONG AS THE SUBJECT OF THE CHILDHOOD BLUNDER IS ACTUALLY YOU.

Don't post a picture of yourself as a child just because you're dressed as a child, playing with your Furby, in a sandbox, etc. This isn't #ThrowbackThursday. If it's an actually embarrassing childhood photo though, then fantastic!

It's okay if other children just so happen to be in the photo, as long as you're the main subject, and the main reason for the blunder.

5 - It’s suggested that you provide a “now” picture, but you don't HAVE to.

If the OP hasn't provided a "now" picture, it’s okay to request one, but don't push it: not everyone wants their current photo on Reddit. Do not go through the OPs post history and post one for them either.

Also, a mere picture of your face is not a blunder. If you want to show how attractive you've become after puberty, head over to /r/uglyduckling. They'll love you there.

6 - Ask permission if there are other people in the photo

Especially if someone else is the subject of the photo. This isn’t the place to get your blackmail on.
